You could put up a greeting card display, so while people were waiting for their prescriptions, they'd say to themselves, "Look at that. I need to get a birthday card for my granddaughter."
Podríes posar un expositor amb felicitacions, així la gent mentre espera les seves receptes, es diuen, "Mira això, necessito una postal per felicitar l'aniversari de la meva neta"
